Trait Implementations

impl Clone for WcagLevel

fn clone(&self) -> WcagLevel

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq for WcagLevel

fn eq(&self, other: &WcagLevel) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
